1 Multi-Function Weighing Indicator Performs many operations, from batch weighing to field bus networking applications. Clearly a Better Value

2 A&D s new indicator, the AD-4402 is designed for batching operations and can also be incorporated into systems using Field Bus such as CC-Link, DeviceNet and PROFIBUS. AD-4402 has almost all the functions, user-friendly operating procedures and software you need for your weighing system. Hopper gate control is done by forecast control mode with 1msec-high speed response. Incorporates Recipe and Mixing modes. Select from 50 + functions for each of the 11 Control Inputs and 11 Control Outputs. Meets Fieldbus requirements by employing CC-Link, DeviceNet and PROFIBUS. Features Large and easy to see blue Vacuum Fluorescent Display (VFD). Uses a ten key pad and function buttons that are designed for ease of operation and understanding. The main display has a 7-digit VFD with 18mm tall characters. The subdisplay has 108, 5mm tall characters and shows the valuesand error comments. Pre-programmed with multiple sequences and functions for filling machines, simple mixing machines and other applications. Stores 100 data for raw materials and 100 data for recipe codes. RS-485 Serial Interface standard feature allows you to link up to 32 units to the display and supports the Modbus function. The Monitor Function shows each operating interface and provides a confirmation on the display. The compact body meets DIN requirements, while minimizing the depth of the indicator to135mm. With the proper optional interface, the AD-4402 is compatible with CC-Link, DeviceNet, PROFIBUS.

3 Multi-Function Weighing Indicator Applications AD-4402 can be incorporated in various applications that integrate complex systems, thereby facilitating a wide variety of sequences, such as basic filling/discharge, recipe, mixing, compensation and preliminary sequences. Mixing System Control by AD-4402 Filling Gate Recipe Ing. Ing. Ing. Ing. Material 5 200kg Material 10 50kg Maximum 10 Material Code Controlled Mixer Exhaust Gate Material 3 80kg Direct Control up to 10 Material Hoppers Full, Medium, Dribble Flow Filling Control Mixing Fan Up to 100 Recipe Combinations All the relay boards, field bus-interface boards are optional. The necessary software is built-in. Nozzle Control Application Nozzle down Supply start Dribble flow ends Nozzle up Judgement Bin-Gate Timer At the judgement, if the supply is short, the re-supply will work until the target amount is supplied. Control output signal for supply Nozzle down output signal This output signal controls the nozzle s movement during filling weighing, which can protect liquid or powder material from contamination. The nozzle movement output signal can be used as a dust-separator movement signal. High Communication Capability Standard RS-485 Overwriting and Memorizing Setting Parameters via PC RS-485 AD-4402 parameters and function settings can be memorized.

4 Here is why we recommend our AD-4402 Multi-Function Weighing Indicator for your weighing system. Sequential weighing mode The sequential weighing mode directly outputs control signals such as supply, discharge, preliminary-fullmedium-dribble flow, recipe and mixing materials and nozzle control without PLC. Interface monitoring function Control I/O, RS-232C,-422,-485 I/F, Current Loop, A/D converter, BCD output, Relay output, Parallel I/O, Analog output, etc. can be monitored to see if they are working correctly. You can see each interface status visually during operation without stopping the weighing system. Interface Monitoring Function Example: Control I/O Input Terminals A1 to A11 Status Output Terminals B1 to B11 Status 11 Control Inputs/11 Control Outputs 50+ functions (such as Full Flow, Over, Under, Discharge Bin, Net Display, etc.) for each of the 11 Control Inputs and 11 Control Outputs, depending on the weighing system. Standard RS indicators can be hooked up to the PLC (programmable logic controller), a PC (personal computer) or other equipment that supports Modbus. This is useful for control commands input and recalling/updating the code memory. Optional Field bus networking interface boards for CC-Link, DeviceNet or PROFIBUS To meet increasing requirements for networking with field bus systems, there are three bus-interface options (CC-Link, DeviceNet and PROFIBUS), which can be hooked up directly to the PLC units. More than two indicators can be hooked up to the PLC at one time. Interactive messages Messages that assist current operations are shown on the display and allow anyone to operate the AD-4402 without an instruction manual. Just follow the interactive setting and operating procedures on the display. Sometimes mistakes happen. When they do, a message is displayed so you can recognize the situation and take corrective steps. Digital Span and Gravity Acceleration Compensation When you cannot use an actual calibration weight due to location, just input the load cell rated output voltage for zero point and full capacity calibration. After moving the calibrated weighing system, recalibrate it by inputting the local gravity acceleration value. Calibrated A/D board The A/D board is calibrated before shipment and guaranteed to 1/500 accuracy. You can quickly replace the A/D board if there is a malfunction. Safety check function This function is used to stop the sequence when an error or an emergency occurs. When the safety function is used, an error code is displayed and an error signal is output automatically to the PLC to stop the system. Up to eight emergency overrides can be installed. Safety Check Function (Error Alarm Signal Output) Trouble occurs Weighing hopper Falling down Detection switches Signal output for full, medium and dribble flows. Error signal System automatically stops Kinds of output signals Weighing sequence error Zero error Alarm 1 Alarm 2 Trouble Error Occurs Install up to 8 emergency overrides They can be aligned with any connector on the Control I/O and OP-05.

5 On the main and subdisplays, a Vacuum Fluorescent Display was used for easy visual recognition. Operation keys are arranged by function for easy setting and recalling the contents. What s more, there are messages for each setting and function and current status on the subdisplay. Even without an instruction manual, you can handle many emergencies. For harsh environment-use such as in moisture, water and dust environments, the AD-4402 display is IP-65 compliant. For speedy and timely operation, keys are larger and functionally arranged. Contents by Code and setting & status messages are displayed on the subdisplay. Alphanumeric input is available using the setting input-keys. Display example The AD-4402 s interactive, easy to see character arrangement and graphics are very user-friendly. The main display has 18mm tall characters and a 7-digit VFD for the weight value displays. The code name, code number, total, set-point, counts, bar graph and judgment can be displayed on the subdisplay. Displays calibration, current status (like setting procedures), error, malfunction and trouble-shooting messages.
